Bei y known that I, PETER C. GREENAWALT, aicitizen of the United States, residing at ;'Readin in the' county of Berks and State of f Pnnsy vania, have invented certain new i and useful Im rovements in Hinges; land I.

do -hereb dec are the following to. bea full, rgclear, an exact description of the invention,

such as will enable others skilled in the art to xwhich it appertains to make and use the same.

-,v inventionirelates to improvements in hinges, and lparticularly to a form of hinge provided Wit means for su porting the leaves with their .faces flush wi't respect to each i5, Vother.- l

plates in con'unction with a hinge desi ed .to'retain the eaves of the hinge flush wit re spect to eachother when in an open condiith this and further objects 1n view the Vinifggentionfooiiiprises certain novel construccombinations, and arrangements of parts as will be hereinafter fully described .p45 and claimed.

In'the accompanying drawings, Figure 1' represents a perspective view of a fragment-- ofa sewinilpachine, illustrating the present;

improved ge applied thereto. Fig. 2 repesents an ed e view of the hinge detached,

the epnnecte plates being indicated in dot- ;fifes and the parts of the hinge being in a folded position. Fig. 3 represimilar view of the same in an extend-l ed-position. Fig. 4 represents afragmentary top plan view of the inge. Fig. 4a represents a longitudinal vertical central sectiontaken through the structure shown in Fig. 4. Fig. 5 re resents a perspective Vview of a modified orm of the hinge. Fig. 6 represents a top plan view of the saine. Fig. 7 re resents an edge view of the hinge disclose in Figs. 5 and in a folded position. Fig. 8

re resents an edge view thereof. eferring to the drawings b .numerals, and particularly with respect to igs. 1 to 4, inclusive, 6 6 indicate leaves of the present improved hinge, each provided with an eye 7 extending inwardly from the inner edge thereof, each of said eyes being positioned in operation inline with eyes 8 8, pio ecting laterally from the opposite sides o a central link 9. The eye 7 of the respective leaves is adapted to be connected with the corresponding eyes 8 of the link 9 by means of a suitable 10. The upper surface of each eye'7 pintle 'to which are secured side strips, from which Aretain the hinge with the u is Hush witli the upper surface of the respective leaves, and the upper surfaces of the eyes 8 are il'usli with the upper surface of the link 9, the upper surfaces of Said link9 and said 6o eyes 8 being in operation iiush with the upper surface of the leaves 6 when the leaves are extended, as indicated in Fig. 3'. The link 9 is of suflicient width to extend beyond the plane of the lower surfaces of the eyes 8 6 5 and'of the eyes 7, and said link in practice is designed to be engaged upon -its opposite sides b the curved portion 12 of stoplates 13 13, xed to the under surface of the eaves 6, preferably by rivets 14. Of course it will l n a; be understood that the stoplates 13 may be The object in view is the provision of stopr leaves 6 in any desired manner, the curved of any desired thickness an secured to the portion 12 of each of said leaves being of sufcient length to engage the corresponding side of the link 9 when the leaves are in an open condition, as indicated in Fig. 3. Itis further to be noted that the link 9 is preferably made up of a central strip of material,

8o are formed eyes 8; but of course the central strip and -the side strips may be formed in tegral, if desired, and the result will be the same. In practice the hinge is adapted particularly or use in connection with dro head scwingmachines, such as is indicated in Fig. 1 of t e drawings, and the stop-plates 13, with their curveda portions 12, are ada ted to per s aces of the leaves 6 in a ilush condition when the top late of the machine is hinged outwardly to orm a leaf. f

In Figs. 5, 6, 7, and 8 I have illustrated a slight] -modiiied form of the resent -improve structure, in whichl 1 in icate leaves provided with suitable eyes 2 2, arranged at the inner edge. A central link 3 is positioned between the leaves 1 and is provided with oppositely-disposed eyes 4'4', extending laterally from the sides of the bar 3, the eyes 4 being positioned to alternate with the eyes 2, so as to fit between the same. Secured to the under surface of each leaf 1 is a stopplate 1, rovided with a curved portion 1."- at the e ge thereof, surrounding the lower portion of the respective eyes 2 and adapted in operation to engage the lower de ending edge of the link 3 for stopping the iiaaves 1 with their upper surfaces in an extended conico IIC

dition, the upper surfaces of the link 3 and surfaces of the leaves l and said e es 2 and 4- being pivoted together by suitab 5. Thus it will be seen-that by the ern 1oy,- ment of a central link provided witlilter- 5 ally-projecting e esy adapted to engage the eyes of the latera ly-disposed leaves, the .link being extended below the eyes,, sto'pplates having curved portions surrounding the eyes may be employed, which will engage the portion of the central link 'extending below tflie.y I eyes and will support the leaves ina'ush condition when extended and will readily permit a folding 'together of the :leaves whens desired,

WhileV I have illustrated the present "i1'n. proved hinge as applied to asewing-machine, it will ofcourse be understood that-the same .may be applied to any structure where it is desirable to have ya stop for su porting'the `leaves of :a hinge in a ilush con ition.
